- T0 1/ZZ whom it m/ay concern.-

Be it known that I, LOUIS SHoLEs, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of .Wisconsin, have invented certain new and useful Improvements in riype Vriters, of .which the following a specification, reference being had tothe accompanying drawings, forming a part thereof.

The main object of this invention is to shift the pivots or fulcrums of type-bars, each having a plurality of type for printing different characters by the manipulation of the keys employed to produce the impression of the type upon the platen.

It consists in certain novel features of conpeculiar arrangement combinations of parts hereinafter particularly described, and pointed out in the claims.

In the accompanying drawings like letters designate the same parts in the several figures.

Figure 1 is a side elevation of a portion of a type-writer embodying the invention, certain parts being broken away and shown in section. Fig. 2 is a vertical cross-section on the line 2 2,'F1gl, and Flg. 3 1s a horlzontal section on the line 3 3, Fig. 1.

a designates a type-bar having a plurality, in the present case two, type b c, for printing different characters. It is fulcrunied or pivoted at d to a shifting lever c, which is in turn fulcrumed or pivotedlat to a fixed support g on the frame of the mac line.

72y is a key or impression lever iulcrumed or pivoted at its rear endlto a xcd support i on the frame and connected. between its ends by a link y' with an intermedia te lever 7c, which is in turn fulcrumed at its rear end to a rearwardly-extending arm of the lever e and is pivotally connected at its front end with the type-bar a by a pin Z, working in a slot in said bar. A retracting-spring m, connecting the lever h with the support i, tends to return said lever and type-bar with their connec-' tions o their normal or initial positions.

n is a key-support provided with guides o and p, in which the stem g of the key 'r is The key-,stem is pivoted in the ripper guide o and on a pin s, passing transversely through the opening in said guide and a longitudinal slot in said stem. The lower guide phas a plurality of openings t, corresponding in shape with thc stem 1 and in number and arrangement with the type l) c i cated by dotted lines on Fig. i. At its lower end the stem q is forked or slotted to loosely,

embrace the lever t, which is curved on its upper edge in its normal position concentrically with the pivot-pin s. A bar or rod t', pivoted at its rear end to a depending arm of the shifting lever c, is pivoted at its iront end to the lower end ot a link w, which is in turn pivoted at its upper end on or in line with the pin s in the upper guide o. The lower end of this link has pins or projections a: loosely embracing the key-stein q and causing it to impart its lateral mover/nent to the bar or rod e and the shifting lever e. A. spring y, connecting the bar or rod c with the lsupport g, tends to retract the key and its stein into and to hold them in their normal printing position, in which the stem stands vertically, as shown in Fig. 1.

The improved shifting and printing mechanism hercinbeliore described operates as follows: By depressing the key r from its normal initial position, in which it shown by full 'lines in Fig. i, the upper or outer type b on the type-bar a is caused to describe the path indicated by is caused to make an impression on the platen, which is indicated in the same ligure by broken circles. It an impression is to be made with the lower or inner type c, the key r 'is thrust backward and the stem q tilted into an inclined position. By this operation the iront end of the shifting lever c and the i'ul- Crum orpivot d of the type-bar rt are carried upward, as indicated by dotted lines, into` position to produce an impression oi .the type c ousthe platen. It now tbckey is de iressed, its stem q being held and guided in tl opening t after the reduced portion vu of the stem passes below the guide p, the type-bar (L will be swung upward'and backward against th'eI platen, the type c describing the path represented by the lower or inner dotted arc, which intersects the upper or outer .are described by the type b at the surfe-ceci the platen or at the printing-point thereon. The

the upper or outer dotted arc and v i'e iront I' limit of its movement When the reduced part luJ oi its stem is brought opposite the constricted passage in the guide p will be carried back by the spring y into its original position, in Which the stem registers with the rear opening t, thus restoring the parts of the mechanism to the required positions Jfor making an impression with the type l) by simply depressing the key r in the usual Way, it Will be understood, of course, that each multiple type-bar is' to have printing and shifting connections With a single key like or. similar to those shown and described.

Various modifications in the construction and arrangement of the parts of the mechanism may be made Without departing rom theprinciple and scope of the invention.

L In a type-Writer the-combination .of a type-bar having a plurality of t e, a shifting lever to which said bar is in crumed or pivoted, an intermediate lever pivoted to said bar and to said shifting lever, a key-lever connected With said intermediate lever close to the axial line ofthe inlcrum of the shifting lever, and connections for-operating said sluiting and key levers, substantially as described.

2. In a type-Writer the combination of a shifting lever, a type-bar iulcrumed or pivoted to said lever and having a plurality ,of type, an impression-lever connected with said type-bar, a vertically and laterally movable key having a stem engaging said impression-lever and connected with said shift- 'ing lever, and guides for said key-stem, one of ing lever and having a stem movable endwise ,in said guides'and pivoted in one of them, one ofsaid guides having a plurality of openings for the key-stein corresplonding 1n numy ber and arrangement with t e number and arrangement of type on the type-bar and connected by a constricted passage, and the keystem` having a reduced part which registers With'said constricted passage'when the key is in a certain position, substantially as described.

Il. In av type-Writer the combination of a shifting lever, a type-bar ulcrumed or pivoted to said lever and having a plurality of' type, a key-support having guides for the key-stem, a key having its stemmovable end- Wise in said guidesand pivoted in one of them,

the other being slotted to permit lateral movement of the stem When the key is in a cer- .y tain position, and a bar connected at one end With said shifting lever and at the other with said key-support by a link which is pivoted key-stem, a key having its stem movable end- Wlse in said guides and pivoted in pne off them, the other guide being slotted to permit lateral movement of the stem When the keyis in a certain position, a bar connecting said stem with said shifting lever, anda spring tending to hold said key-stem in its normal position, substantially as described.

In witness whereof hereto aflix my signa-V ture in presence of two Witnesses.
